To all whom it may concern:

Be it known that 1, Crane H. SMIT a citizen of the United States, residing at 'lonica, 1n the county of La Salle and State of llllinois, have invented certain new and useful lmprovements in Gasolene-Motor Respirators, of which the following is a specification, reference being had to the accompanying drawings.

. My invention relates to means providing for the passage of vapor into the cylinders of an internal combustion engine, and particularly to provlde means for passing vapor into said cylinders which will prevent the formationof carbon therein, this vapor also.

, is adapted to be connected to the manifold of the engine and whereby a mass of absorbent material may be kept moistened with a liquid of predetermined character and whereby air may be drawn through this mass of absorbent material so as to take up the liquid and carry it into the manifold and so to the several cylinders of the engine.

Still another object of the invention is the provision of means whereby the passage of the liquid compound to the chamber con taining the absorbent material will be automatically prevented when the engine stops and automatically prevented when the absorbent material is fully saturated, the further passage of said fluid compound, however, being permitted when the predetermined degree of saturation has been lessened or when the device again starts up.

With these and other objects in view, my invention consists in the details of construction and arrangement hereinafter more fully set forth.

lln order that those skilled in the art to which my invention appertains may underepeelflcation of Letters Patent.

stand it, ll will proceed to describe the con- Patented .ltpr. lid, lath. Application tied hotelier 5; Hit. @erial Ito. nearer.

struction and operation of the same, refer- I ring by numerals to the accompanying drawlngs, 1n which, Figure l is a side elevation showing my improved apparatus in place upon an automobile which is shown in broken lines; Fig. 2 IS a side elevation on enlarged scale of thepapparatus; Fig. 3 is a vertical section partly in elevation and with the connection roken away; Fig. 4: is a cross section on the line a-a of Fig. 3; and Fig. 5 is a similar view on the line 6-4) of Fig. 3.

Similar reference letters indicate like till parts in the several figures of the drawin v l is a riming cup for the mixture herein, after re erred to, the supply from which is controlled by a cock 2, and when delivered it is contained in a font or reservoir 3 from which the contents are conducted through a supply tube tprovided with a cut ed cock 5.

6 is a vent tube leadin from the u per end ofthe font 3 tn the ower end o the mixing chamber 'l' which is packed with asbestos as clearly indicated at Fig. 3.

'lhe font and the mixing chamber are connected by a threaded and flanged ring 8 between the lower extremity of which and .an annular shoulder near the upper end of the mixing chamber are secured two thin sheet brass diaphragins 9 provided with orifices 10, and between these diaphragms is confined two thinbrass screens ll.

Passing centrall through the diaphragms and screens and t rough the bottom of the mixing chamber 7, is a tube 12 having a flanged head 13 with a perforated cap it between which and the head is confined a screen 15 (see Fig. 5) and the lower end of thetube 12 is secured in position by a flanged nut 16, and connected with the tube 12 is a smaller tube 17, connected as shown at Fig. 2 with a manifold block 18 provided with belt orifices 19. r

The manifold block is provided with minute orifices 20 in alinement with the tube 17. The inlets to the mixing chamberfrom the supply and vent tubes are on opposite sides as" clearly shown and to prevent any clogging of the same, a wire screen 21 is arranged between the asbestos packing and the open ends of the tubes 4 and 6 as clearly shown at Fig.

22 is a flared entrance for atmospheric air whereby a current of air may be drawn through the mixing chamber 7 upon each suction stroke, for the purpose of controlling the amount of air entering through the member 22. This member is provided with a butterfly valve 23 with a controlling arm 24 which is so arranged as to be accessible to the operator, and it is also formed with a well 25 for receiving by gravity any foreign body which may pass the butterfly valve.

It is to be noted that the inlet openings in the head 14 are disposed above the screen 11 so that the air passing into the mixing chamber through the air inlet opening 22 must pass through the packing 7 absorbing the liquid with which the packing is saturated and that the air and vaporized liquid will be thoroughly mixed and intermingled by the screen 11 before the air can have access to the perforations in'the head 14 and before the air can pass into the manifold.

The pipe 6 is for the purpose of normally permitting the liquid contained Within the font 3 to flow out through the pipe 4: and

into the lower end of the mixing chamber.

As the liquid flows out of the pipe 4: air will pass from the mixing chamber by way of the pipe 6 into the upper portion of the font 3, thus keeping the air pressure balanced. If, however, too great a supply of liquld passes through the pipe l, and as a consequence the liquid in the bottom of the mixing chamber rises so as to close the inlet end of the pipe 6, then the passage of airinto the upper portion of the font 3 will be prevented, and as a consequence the liquid in the font 3 will not flow downward through the pipe 4 until the level of the liquid in the mixing chamber has been reduced. Thus when the engine stops the liquid will slowly rise within the lower portion of the mixing chamber until this vent pipe 6 is closed, or if the absorbent material 7 has been'thoroughly saturated, then any excess of llqllld will gather in the lower portion of the mixing chamber and close up the vent, this action automatically preventing the feeding of liquid to the mixing chamber from the font. As soon as the engine starts up, or as soon as complete saturation of the absorbentmaterial has been lessened the flow of liquid from the font 3 will be again started.

Having described the construction and assembled arrangement of the apparatus, I will now explain the manner in which it is connected in operative relation with an enine.'

The block 18 which is arranged between the manifold and the carbureter is secured in place by removing the bolts employed to connect the carbureter to the intake manifold. 'lhe carbureter and the block 18 with surfaces is slipped on. The carbureter is readjusted and the bolts are replaced, and it will thus be seen that the intake from the apparatus will be between the carbureter and manifold. The mixture which I have found espeeially adapted for use in the font iscomposed of equal parts of pure glycerin, wood alcohol and hydrogen dioxid for the reason that in the chemical action moisture is obtained from hydrogen dioxid which when broken up forms water and free oxygen.

This free oxygen and the breaking up of the alcohol and glycerin form oxidizing agents which have a strong chemical affinity for carbon and with which they combine to form carbon dioxid gas which passes out the exhaust.

From the construction and arrangement shown and described, it will be seen that the asbestos" is kept saturated with the compound and that the compound is readily drawn into the engine by the strong air current passing through the butterfly valve and the asbestos and screens.

The several parts can be readily manufactured and assembled, and can also be easily disassembled when necessary and there is nothing to get out of order as the only part involving motion islthe butterfly valve.

All connections between the tubes leading to the font and the mixing chamber are made by the employment of suitable nuts and screw threads.

I do not wish to be confined to the use of any special compound as any compound producing the results named may be used, and likewise I do not wish to be confined to the exact details of construction, dimension, or

. proportions of the several parts as they may be varied without departing from the principle of my invention which involves the broad idea of arranging a respirator between the carburetor and the manifold.
